iPhone 6S Plus makes a rattle vibration sound.

So my iPhone 6s plus is making a weird buzzing/rattling sound when it vibrates. It is normal? It also has a weird popping sound when using 3D touch.

I can't speak for the buzzing sound when vibrating. How long have had the device?

As far as the popping sound with 3D Touch, it could be the display not being seated properly or the adhesive separating. Is the popping sound in a specific area or all
Over?

The popping noise is from the vibration of 3d touch. Whenever I turn the phone upside down, the vibration sound would be more quieter whereas when the phone is in regular position, i can hear a loud rattling/buzzing sound. Here is the exact issue shown in the video below.
